Honestly, a Spider-Man clone is really hard to write without breaking away from Spider-Man's everyman status. It's part of why I was never crazy about Ben Reilly. Writers treat his identity issues as being the same as that of non-clones (which is absurd) or go full-in on what it's like to be a literal duplicate of another human being... which no one who is alive can relate to, and at that point Ben is more of a sci-fi character than an everyman.
